Projects in Switzerland

[Bazinga]

Hi,

was this VTOL airplane Project of 1933,which invented by Mr. Leuenberger a Dutch design ?.

This looks very much a German design. Even the image which was from a German report.

In the upper left corner, there are several columns, the first labelled "Jahr" (year), the second "Land" (country).
And even in those stamp sized pictures, the country code "CH" is visible.

Searching for "Leuenberger" and "Heckstarter" brings the same data base as a pure text file, without pictures,
and there it's more obvious, especially when compared with other entries:

So, it's not Dutch, but Swiss.

Korsa T.1 / T.2

The Korsa I was also featured in Aero Digest February 1928 as Alstetten-Zurich Korsa I as a design from Hugo Schmid.

A video on the EKW C-36:

The very strange is EKW,which after designed DH-1,2 and up to M-8,it
converted the series to indicate the year of built or created,such as C-35.

Not so strange. It represents a shift in Swiss military designation styles.

The original K+W/EKW internal 'DH' designations stood for Doppeldecker Häfeli (ie: Biplane Häfeli). But those designs also received parallel 'M' (for Militär) designations. The latter changed to non-parallel 'MA' (for Militär-Apparat) designations beginning with the MA-6 (despite still being designed by August Häfeli).

The C-35 was part of a new military designation system. The prefix codes look rather German but, I suspect, that they sprang from the in-service types being replaced. So, the D-3800 series replaced licensed Dewoitine fighters while the C-35 (and then C-3600 series) replaced Fokker C.V recce types.
